Scale Development: Theory and Applications, by Robert F. DeVellis and  new co-author Carolyn T. Thorpe, demystifies measurement by emphasizing  a logical rather than strictly mathematical understanding of concepts.  The Fifth Edition includes a new chapter that lays out the key concepts  that distinguish indices from scales, contrasts various types of  indices, suggests approaches for developing them, reviews validity and  reliability issues, and discusses in broad terms some analytic  approaches. All chapters have been updated, and the book strikes a  balance between including relevant topics and highlighting recent  developments in measurement while retaining an accessible, user-friendly  approach to the material covered.
